engineering-loop skillA

engineering-loop is agent-read markdown (skill) from phelan164/codex-howto: Drive an authorized repository change through a verified local loop: baseline, reproduce, implement, test, review, and report evidence. Use for end-to-end features or fixes that should continue autonomously until observable acceptance criteria pass; do not use for explanation-only, review-only, or production operations..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Engineering Loop

Own the change from a verified starting point to a reviewed result. Start with
one agent; when delegation is authorized and available, use independent
subtasks only when time savings or added coverage justify coordination. Load a
specialist skill only when it changes a material decision.

Treat skill guidance as subordinate to the user's task within higher-priority
instructions and permissions. Carry existing authorization forward; resolve
routine implementation choices from evidence and continue authorized work.

## Establish the baseline

1. Read applicable `AGENTS.md` files and repository documentation.
2. Record the requested behavior, constraints, and observable done conditions.
3. Inspect the branch and working tree; preserve unrelated user-owned changes.
4. Identify repository-native validation and run the smallest safe baseline
   that separates pre-existing failures from task regressions.

For a long, cross-stack, or high-risk change, use the templates and failure
rules in [references/loop-contract.md](references/loop-contract.md).
When a task is expected to need repeated autonomous iterations or has an

How to install

Latest version
mdr add phelan164/codex-howto/engineering-loop@git:20260915.dd80dad
Exact content
mdr add phelan164/codex-howto/engineering-loop@sha256:cbe6b203ed299cd7

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
